Some people prefer the stompswitch rather than Boss' switch design. Sometimes we just want a discrete or unique looking pedal that doesn't look like every other pedal out there. The predrilled casing pictured above allows for a quick turn around time.

This new version is far more accurate to the original than the standard Phase 90.

The plan was to keep it simple for ease of use and to save space while traveling. The tremolo has depth and rate controls, the reverb has volume and tone controls. I'm surprised more reverb pedals (and delay pedals) don't have a high cut control to better match an overly bright guitar or amp.FX Doctorhttp://www.blogger.com/profile/14139149291691697016noreply@blogger.comtag:blogger.com,1999:blog-4655963564268845189.post-90199469208307494522010-10-11T11:26:00.001-04:002010-10-11T11:39:31.084-04:00Cease.Transmission Prototype 2Here's another Cease.transmission prototype this time without an LED to prolong battery life.

The Metatron is a project I've been working on for years but never had time to complete. In the video I am using a nearly completed version of the most recent prototype. The pedal is based on the Maestro Filter Sample/Hold pedal which has been discontinued years ago. While sonically they may be similar, the signal path is 100% original and in no way a copy of the Maestro.
